It is clearly a crash on close , with lensfun involved , btw do you have also installed gimp-lensfun ? do you get this crash often ?

Every attempt (about 10) after installing Fedora 24 ended with a crash.
After your message I installed gimp-lensfun and there is a slight change in
the ufraw behaviour: when sending result to Gimp - Gimp starts, progress bar 
is running and then I get an error dialog:
"Opening '/tmp/DSC_4925.NEF_8RTSJY.ufraw' failed: Procedure 'file-ufraw-load' returned no return values"
There was no change in ufraw-gimp behaviour.

Goggling around https://bugzilla.redhat.com/show_bug.cgi?id=947988#c8 says:

Sorry forgot to add, as mentioned above downgrading lensfun to 0.2.5-6 does restore functionality.

Could be again ufraw/lensfun vector , I may do one build in copr , may you try one build without lensfun support ?

I didn't try downgrade yet, tomorrow I will check the other computer with Fedora 23 for the lensfun version (though it is 32bit distro). The last version on F23 x86_64 worked (I used it about a month ago and I update imediately when I find new updates).

If you can provide the build I will test it. I don't have any experience with the copr yet - I believe you mean copr.fedorainfracloud.org.

Oldest lensfun version present in Fedora 24 x86_64 repos is 0.3.0 so I can't try version 0.2.5-6.
On Fedora 22 32 bit (I misspoke in the last reply) I have ufraw working with these installed packages:
gimp.i686         2:2.8.16-1.fc22  @updates
lensfun.i686      0.3.0-6.fc22     @updates
ufraw-common.i686 0.21-1.fc22      @updates
ufraw-gimp.i686   0.21-1.fc22      @updates

Current workaround: 
1. Save edited image creates a ppm file (and crashes too - I'm not sure whether I should file new crash report or just mention it here),
2. convert file.ppm file.png
3. Open file.png in GIMP and do the rest of the editing work.

Sorry for all the comments.
Ufraw crashes after clicking on ANY of these buttons: Cancel, Save, Send-to-GIMP, X - close the application in the upper right corner of window (depending on the current window manager theme) although after clicking to Save the ppm image is saved successfully (as mentioned above).
System always offers sending crash report - should I do it for all the cases (read: clicking on each button)? Can it help to find the common denominator of the crashes?

thanks for all reports , feel free to send more , works with lensfun.i686      0.3.0-6.fc22  , but on F24 we have 0.3.2 , so you still don't exclude a lensfun incompatibility ? , soon I have a little spare time I will send build (with lensfun) to copr ...

Antoni or Moravcik can you test this builds [1]? :

https://copr.fedorainfracloud.org/coprs/sergiomb/builds_for_Stable_Releases/build/380090/

and report it back ? 

[1] 

    dnf copr enable sergiomb/builds_for_Stable_Releases 
    dnf update ufraw

from the very first tests, it seems to work, at least when opening a PEF file from a Pentax Dslr

I can confirm success on both ufraw and ufraw-gimp-plugin from your build. 
No crashes on Cancel, Save or Send-to-gimp. Passing result to GIMP work in 
both the ufraw program and the plugin, also saving image to ppm file seems to give correct output. Tested on VM Fedora 24 x86_64 with NEF file from Nikon dslr.

I'm happy this worked and if there's anything more I should do about it, please let me know.

I'm happy too, as workaround I'm building officially the same package (without lensfun) , we checked Debian , also have the same problem [1], I will see where it is fixed

Sorry for showing up late, but I didn't have the time to look at this earlier. Sergio, thanks for taking up the slack :).

I'm not very happy about working around this issue by building without lensfun, because it removes a feature that I believe many users use. On the other hand, I accept that this is better than ufraw crashing left and right until we have a real fix ;).

In order to get to the bottom of this, here's the (IMO) relevant part of the backtrace:

--- 8< ---
Thread 1 (Thread 0x7feb7260ca40 (LWP 5806)):
#0  lfModifier::~lfModifier (this=0x0, __in_chrg=<optimized out>) at /usr/src/debug/lensfun-0.3.2/libs/lensfun/modifier.cpp:270

No locals.
--- >8 ---

Looking at frame #1, here this is NULL, this means that lf_modifier_destroy() is called with a NULL value in frame #3 -- frame #2 is just a C-API wrapper around the C++ code of the library. Here's the affected code from frame #3:

--- 8< ---
void ufraw_close(ufraw_data *uf)
{
    ...
#ifdef HAVE_LENSFUN
    lf_modifier_destroy(uf->TCAmodifier);  <-- line 770, where the crash happens
    lf_modifier_destroy(uf->modifier);
#endif
--- >8 ---

I've skimmed over the rest of code that touches on ->TCAmodifier (and ->modifier) and didn't find that it's safe to assume that these members are always set. To me, the code should first check that the relevant members are not NULL before attempting to destroy the object. What do you think, Sergio?

This is temporary fix "until we find a fix". 
From https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=787569 and other reports is not just a crash also result in artifacts in some images ... so shouldn't be so easy to fix . 

I just report it upstream: https://sourceforge.net/p/ufraw/bugs/406/

*** Bug 1348725 has been marked as a duplicate of this bug. ***

Nils Philippsen, may I or should I , push the package to stable ? upstream didn't reply yet !

ufraw-0.22-2.fc24 has been pushed to the Fedora 24 stable repository. If problems still persist, please make note of it in this bug report.

Hey Sergio, any news on this with regards to a "real" fix, i.e. one that restores lensfun functionality?

http://ufraw.cvs.sourceforge.net/viewvc/ufraw/ufraw/?sortby=date#dirlist

we have 2 patches in cvs , 
1 - Add patches to use RGB channel multipliers from ID file and implement noExit option. The Cancel button acts as Quit when noExit is set. Patches were found in the ufraw-devel archive.

2 - Fix bug #407: Wrong variable type for find_green() return value.

First patch mention cancel, so maybe we may try apply it on rpm package, enable lensfun again and send the package to updates-testing. 

what do you think Nils ?

Do you mean both changes? I don't see how the second one is related, but you have been more involved in this issue... Anyway, sounds good to me.

Antonio and  Nicu Buculei can you test this new version ? please

No, just tried nut it doesn't work for me.

When I exit from Ufraw Gimp says:
Opening of /home/antonio/Immagini/xxx.PEF failed. Procedure "file-ufraw-load" has not given return values.

(not sure of translation)

I don't know if is ask too much but can you send me, offlist , one image that crash with ufraw ?  too see if is the image problem ? I also could do other tests ...   

We have other reports that can use ufraw with lensfun without any problem, I also don't had any problem .

I have found it, please check if it was solved. Have a look at comment #15.

But now Ufraw crashes also after saving as jpeg file.

how you save as a jpeg file ?  I used "export as" .jpeg in gimp and no problem.

In ufraw after load img, I press cancel and no problem.

I have a pretty standard configuration.

I repeat once again my standard workflow.

When I click on a raw file I should get the opening of the Ufraw-gimp, I work on the curve, color, saturation and whatever I need. Then I click on OK on the right bottom of the ufraw plugin, I Gimp starts....in Gimp if I click on Save I get a xcf image, If I use export as I get a jpeg image or some other extension.

I am surprised that you can work on a PEF file, as I could reproduce this behaviour (I mean the crash) on three different machines, as in the old bug ...I assume that from ufraw-0.22-2. to -3 only changes connected to lensfun have been included. But what surprises me more is that I cannot include the workaround of the other guy about the *magic line deletion.

so only to resume - only for PEF files
1) Ufraw (as standalone) works and save any extension of image, then closes (and I get also the horrible message Oops it seems that ufraw crashed- and  a report has been sent - I do not where, but it is not a my problem-
2) UFraw-plugin try to open Gimp but I get the message already reported in my comment #40

I note that the other Italian guy that suggested the work-around was disappointed and left the bug alone (and I think that he left Fedora)

No idea how to help from hereon

My situation now is similar to what reported in comment #18

On my side I do not see any improvement since last July

Hi, 
Thanks for all details , my tests was on F23 sorry , now I can reproduce the problem on my F25 test machine , like you said every time we close ufraw , pop-ups one error message. 
I will see, if I can fix the problem and I will report back give me some days please.

Thanks.

May I help with additional tests??

Hi,

> May I help with additional tests??

No , the samples that I have are enough. 
I'm writing just to add one update, by accident lensfun was also be updated in f23 from 0.3.1 to 0.3.2 . we are rebuilding package that depend on it and I had test it ufraw-0.22 and in F23 these crashes doesn't happened, in F24 with last update of lensfun still crash ... .

I don't understand, same version of lensfun, ufraw and gimp and works in F23 and does not work in F24+ (also crash in F25) .

ufraw-batch crashes here in f24. 
ufraw-0.22-3.f24.x86_64, lensfun-0.32-5.f24.x86_64

My fix:

Good catch Franco Comida. Now I had review comment 28 where Nils Philippsen already had suggest a similar solution, at the time I didn't catch it but TIL read a little better one gdb backtrace . 
Meanwhile I will report the fix to upstream .

Thanks
